ed, stemmed, and other forms of glassware;

and it consists in forming the bowl or body by blowing it upon theblow-iron without the use of molds, and then ,aflixing the base, foot,

To enable those who are skilledin the art to which my inventionappertains to fully understand its nature and make and use the same, Iwill briefly describe the present state of the art wherein I claim myprocess to be an improvement. H l

It is considered impracticable to press glassware as thin as can be doneby blowing; consequently all the finer articles of were are blown,andhave a foot or foot and stem formed by hand, which isnecessarily roundfrom the rotary motion required in working. An addi tional gathering ofglass is added ta the erea pressed foot or stem is'united to--a blownarticle or bowl, has been made'by blowing the bowl against a pressedfoot or stem with the mold and foot'stationary, or'by blowing the bowlagainst a pressed footor stem placed on a rotary table; but all of thesemethods are objectionable in a greater or less degree, on account of im'rfect joints at the point of contact of the foot, and other mechanicaldifliculties we'll knownto'the trade,'and are very expensive,

j requiring skilled labor, tedious, and laborious. To overcome thesedifliculties and accomplish the same result- -viz'., of producing ablown article of v glassware with a pressedglass foot," stem, or knob ina speedy, perfect,and nomical manneris the object of my invention.

own bowl with the pressed" ;o :benished in any m nn ifi t d, an s Inorderto illustrate more. fully my inveni tion I will describe theapparatus employed andmode of operation,reference being bad to thedrawing, in which- Figure 1 is a front elevation of an ordinary press;Fig. 2, side elevation; Fig. 3, vertical central section; Figs. 4, 5,detail views.

' Like letters of reference refer to like parts. In the drawing, Arepresents the body of a press, similar to those in general use, havinglegs a a of suitable length to raise the press the requisite height fromthe door to admit of a blow-iron, with anarticle thereon, being placedin a vertical position underneath the press. B is a guide-plateor-iron-rest, made self-adjusting by means of spiral springs b b,secured to cross-piece c of the standards, and is provided with asocket, d, for. the receival of the -endof the blow-iron. D is aprojecting guide-arm secured to cross-brace c. E is a foot-mold placedon, the press ready for opera-v tion. The mold is provided with a bottomplate, 1, having a beveled slot or passage-way, 70, extending from thecenter to theouter edge, to admit of the removalof the two articles whenjoined together. This plate sets imme .diately' over and parallel with asimilar pas bowl thereon, ,is placed,' on thespring guiderest under thecenter of the mold, and forced do wn sufiicient topermit the placing ofthe bowl in thecavityof the-mold, where it is held. by the pressure ofthe springs, it being guided into position by the inclined sides of thecentral'opening-inthe bottom plate of. the mold. At-this stage of theoperation molten glass is placed in the mold and thd plunger forced downupon it, which forms the foot and presses it upon the blown vessel-orbowlat "ration. The article is then ready to readily removed from thepress by simply opening the foot-mold, the slots or passageways in thebottom plate of the mold and press permitting the article being takenout sidewise.

By my process a knob, foot, or stem of any desired shape,-such as anoctagon, hexagon, squafre,-round, or each or all combined, or of anydesign, can be united to a blown vessel or \bowl in a very rapid,effective, and economi'c'al manner, thus snbstitutingmechanical devicesfor skilled labor, and saving a large percentage in the cost ofproducing the finer classes of ware, with the additional advantage ofvariety in shape and design.

The bowl can be disconnected from the blow-iron and placed under thefoot-mold to receive the foot; but as the cup-foot has usually to beformed or finished afterward, being reheated or f warmed in for thispurpose, I deem it best to retain the bowl on the blowiron while;pressing on the additional piece of glass.

I am aware that handles have been formed and affixed atone and the sameoperation upon pitcher's, lamps, ,amdsnch like handled articles, whicharticles '(pitcliers,\-Stc.) had previously been formed by blowing intoamold, the same being commonly known as blow-over glassware. Tbis",.therefore, I lay no claim to, my invention relating to 'articlesthe body or .bo'wtof which is formed entirelylby blowing,

and without the useof a mold.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In a machine for forming glassware, the press A, mounted upon theframe a a, and pro= vided with the slotted bed-plate cc, substain'gially as described, and for the purposes specig 2. In a machine forforming glassware, in combination with the mold E, the removable platef, having a beveled slot or passage-way, K, extending from oenter tocircumference,

substantially as. described, and for the purposes specified.

3. In a machine for forming glassware, the self-adjusting rest /B,substantially as described, and for the purposes specified.

4. In a machinefor forming glassware, in combination with the guide-restB, the guidevarm D, substantiallyasdescribed, and for the purposesspecified.

5. The process'of forming glassware, consisting in forming the body orbowl by blowing it up dn the blow-iron without the use of molds, andthen affixing the base, foot, ste n, or other finishing part, by meansof molten glass pressed in a mold'thereon, substantially as described.
